Spring @Configuration bean created in @Bean method not enhanced by CGLIB

Question

I'm trying to create a MainConfig that imports another Config by using an @Bean method instead of @Import like this :

@Configuration
public class MainConfig {

  @Bean
  public Service service() {
    return new Service(infrastructureConfig().database());
  }

  @Bean
  public OtherService otherService() {
    return new OtherService(infrastructureConfig().database());
  }      

  @Bean
  public InfrastructureConfig intrastructureConfig() {
    return new InfrastructureConfig();
  }

}


@Configuration
public class InfrastructureConfig {

  @Bean
  public Database database() {
    return new Database();
  }

  ...
}

When using this technique, the Database is created twice because Spring doesn't seem to consider the @Configuration annotation on InfrastructureConfig. When using @Import, it works fine.

I don't want to use @Import because I want to mock my InfrastructureConfig like this :

@Configuration
public class TestConfig extends MainConfig {

  @Override
  public InfrastructureConfig infrastructureConfig() {
    return mock(InfrastructureConfig.class);
  }
}

Am I missing something or it is not supported ?

Thanks

I opened a Spring ticket SpringSource JIRA and they said that it is a known limitation and it is working as designed.
